Boy's beachwear
Not sure how old this photo is, but it is photographic evidence that boys swam completely naked in the presence of clothed girls. In this photo, the boy stands there stark naked in the presence of three suited girls. He doesn't seem to mind being nude in front of them, nor do they seem to object to him standing inches away from them wearing his birthday suit!

Excellent photo such ashame this is no longer the norm
Unfortunately the photo is no longer available.
Was a nice photo, was as described a boy casually and comfortably nude at the swimming pool amongst clothed girls. Just how swimming should be.
I has been told that this has been photo-shopped. However, I wasn't there. However, in competitive swimming, boys and girls would not be swimming together.
